Underwater World in Pattaya is an aquarium featuring over a hundred meters of indoor walk-through tunnels where you can observe both salt-water and freshwater fish species including Sharks and Rays, Arapaima and Freshwater Rays.
Other activities and attractions at Underwater World include a Jelly Fish zone, Otter tank, Reptile zone, Sea Turtles, a touch pool, and fish-feeding pool.
Underwater World is well worth a visit, especially if you have children, but in my opinion – entry tickets (unless discounted) are a little bit expensive – in relation to the time you spend there.
It will take an hour at most to see everything at Underwater World, but there’s several more attractions within easy reach of Underwater World. Pattaya Floating Market is just 3.4 kilometers further south on Sukhumvit highway, Mimosa is 6.6 kilometers further south, and Cartoon Network Water Park is 12.7 kilometers south. You can reach all of those by hopping on a white baht bus.
If you have your own transport, use Grab, or charter a private vehicle and driver – you could continue on to Nong Nooch Gardens, Ramayana Water Park, khao Chee Chan (Buddha Mountain), Silver Lake Vineyard, Upside-down House, and Swiss Sheep Farm

How to Get to Underwater World
If you can make your way by baht bus or motorcycle taxi to the southbound side of Sukhumvit highway you can then take the white baht bus all the way to Underwater World for about 10 baht per person. From the South Pattaya Road junction it’s a distance of about 2.2 kilometers, watch out for it on the right-hand side of the highway, just a few meters past Makro.
Alternatively, you could use the GrabTaxi App.

The main feature of Pattaya Underwater World is the walk-through tunnel (photo above) which features both marine and freshwater fish zones.

The daily feeding times are a crowd pleaser, a diver enters the water and feeds the fish by hand (see photo above).
Verdict: On the whole I think it’s a good day out, but expensive unless you can get in for Thai rates or purchase cheaper entry tickets online. Best to take your time in the tunnel and make sure you get some value for money. The best feature for me was the rays, but I think it’s also a great educational day out for children.
